DETAILED DESCRIPTION OF THE DRAWINGS

In one aspect, a disclosed method for a user to remotely view multimedia content received over an MCDN includes transmitting first multimedia content from an MCDN service provider to a first MCDN terminal device configured to display the first multimedia content. In response to a user request for remote viewing of the first MCDN terminal device display, the method may further include duplicating the first multimedia content displayed on the first MCDN terminal device, the duplicate multimedia content including the first multimedia content, for transmission to a second MCDN terminal device. The method operation of duplicating may further include transcoding the duplicate multimedia content into a format suitable for the second MCDN terminal device. The method operation of duplicating may still further include obtaining digital-rights management (DRM) authorization to perform said duplicating.

In some instances, the method further includes transmitting the duplicate multimedia content to the second MCDN terminal device. The duplicate multimedia content may be transmitted to a terminal service executing on the second MCDN terminal device. The first MCDN terminal device and the second MCDN terminal device may be selected from the following device types: a television, a personal computer, a gaming console, and a mobile multimedia device. The first MCDN terminal device and the second MCDN terminal may be of different device types or of the same device type. The mobile multimedia device may be configured for wireless telephony communication, while the method operation of duplicating may further include transmitting the duplicate multimedia content to a mobile content management server that is coupled to a wireless transmission network providing wireless network service to the mobile multimedia device.

In a further aspect, a disclosed CPE for use within a client configuration of an MCDN includes a processor, a network adapter, and memory media accessible to the processor, including instructions executable by the processor. The processor instructions may be executable to receive first multimedia content from an MCDN server via the network adapter, and send the first multimedia content to a first MCDN terminal device coupled to the CPE and configured to display the first multimedia content. The processor instructions may further be executable to duplicate the first multimedia content displayed on the first MCDN terminal device, the duplicate multimedia content including the first multimedia content, and send the duplicate multimedia content to a second MCDN terminal device coupled to the CPE. The first MCDN terminal device and the second MCDN terminal device may be coupled to the CPE via a fixed network.

In some embodiments, the CPE further includes a local wireless network adapter configured to provide wireless access to at least one of the first MCDN terminal device and the second MCDN terminal device.

The memory media may also include instructions executable to send the duplicate multimedia content to a terminal service executing on the second MCDN terminal device. The memory media may further include instructions executable to receive user input for selecting a terminal service on the first MCDN terminal device or the second MCDN terminal device. The memory media may yet further include instructions executable to receive user input for displaying an indication of transcoding between the first MCDN terminal device and the second MCDN terminal device. The memory media may also further include instructions executable to receive user input for displaying an indication of DRM for the duplicate multimedia content.

In the following description, details are set forth by way of example to facilitate discussion of the disclosed subject matter. It should be apparent to a person of ordinary skill in the field, however, that the disclosed embodiments are exemplary and not exhaustive of all possible embodiments.

Throughout this disclosure, a hyphenated form of a reference numeral refers to a specific instance of an element and the un-hyphenated form of the reference numeral refers to the element generically or collectively. Thus, for example, widget 12-1 refers to an instance of a widget class, which may be referred to collectively as widgets 12 and any one of which may be referred to generically as a widget 12.

Turning now to the drawings, FIG. 1 is a block diagram illustrating selected elements of an embodiment of MCDN 100. Although multimedia content is not limited to TV, video on demand (VOD), or pay-per-view (PPV) programs, the depicted embodiments of MCDN 100 and its capabilities are primarily described herein with reference to these types of multimedia content, which are interchangeably referred to herein as “multimedia content”, “multimedia content programs”, “multimedia programs” or, simply, “programs.”

The elements of MCDN 100 illustrated in FIG. 1 depict network embodiments with functionality for delivering multimedia content to a set of one or more subscribers. It is noted that different embodiments of MCDN 100 may include additional elements or systems (not shown in FIG. 1 for clarity) as desired for additional functionality, such as data processing systems for billing, content management, customer support, operational support, or other business applications.

As depicted in FIG. 1, MCDN 100 includes one or more clients 120 and a service provider 121. Each client 120 may represent a different subscriber of MCDN 100. In FIG. 1, a plurality of n clients 120 is depicted as client 120-1, client 120-2 to client 120-n, where n may be a large number. Service provider 121 as depicted in FIG. 1 encompasses resources to acquire, process, and deliver programs to clients 120 via access network 130. Such elements in FIG. 1 of service provider 121 include content acquisition resources 180 connected to switching network 140 via backbone network 170, as well as application server 150, database server 190, mobile content management server 162, and content delivery server 160, also shown connected to switching network 140.

Access network 130 demarcates clients 120 and service provider 121, and provides at least one connection path between clients 120 and service provider 121. In some embodiments, access network 130 is an Internet protocol (IP) compliant network. In some embodiments, access network 130 is, at least in part, a coaxial cable network. It is noted that in some embodiments of MCDN 100, access network 130 is owned and/or operated by service provider 121. In other embodiments, a third party may own and/or operate at least a portion of access network 130.

In IP-compliant embodiments of access network 130, access network 130 may include a physical layer of unshielded twisted pair cables, fiber optic cables, or a combination thereof. MCDN 100 may include digital subscribe line (DSL) compliant twisted pair connections between clients 120 and a node (not depicted) in access network 130 while fiber, cable or another broadband medium connects service provider resources to the node. In other embodiments, the broadband cable may extend all the way to clients 120.

As depicted in FIG. 1, switching network 140 provides connectivity for service provider 121, and may be housed in a central office or other facility of service provider 121. Switching network 140 may provide firewall and routing functions to demarcate access network 130 from the resources of service provider 121. In embodiments that employ DSL compliant connections, switching network 140 may include elements of a DSL Access Multiplexer (DSLAM) that multiplexes many subscriber DSLs to backbone network 170.

In FIG. 1, backbone network 170 represents a private network including, as an example, a fiber based network to accommodate high data transfer rates. Content acquisition resources 180 as depicted in FIG. 1 encompass the acquisition of various types of content including broadcast content, other “live” content including national content feeds, and VOD content.

Thus, the content provided by service provider 121 encompasses multimedia content that is scheduled in advance for viewing by clients 120 via access network 130. Such multimedia content, also referred to herein as “scheduled programming,” may be selected using an electronic programming guide (EPG), such as EPG 316 described below with respect to FIG. 3. Accordingly, a user of MCDN 100 may be able to browse scheduled programming well in advance of the broadcast date and time. Some scheduled programs may be “regularly” scheduled programs, which recur at regular intervals or at the same periodic date and time (i.e., daily, weekly, monthly, etc.). Programs which are broadcast at short notice or interrupt scheduled programs are referred to herein as “unscheduled programming.”

Acquired content is provided to content delivery server 160 via backbone network 170 and switching network 140. Content may be delivered from content delivery server 160 to clients 120 via switching network 140 and access network 130. Content may be compressed, encrypted, modulated, demodulated, and otherwise encoded or processed at content acquisition resources 180, content delivery server 160, or both. Although FIG. 1 depicts a single element encompassing acquisition of all content, different types of content may be acquired via different types of acquisition resources. Similarly, although FIG. 1 depicts a single content delivery server 160, different types of content may be delivered by different servers. Moreover, embodiments of MCDN 100 may include content acquisition resources in regional offices that are connected to switching network 140.

Although service provider 121 is depicted in FIG. 1 as having switching network 140 to which content acquisition resources 180, content delivery server 160, and application server 150 are connected, other embodiments may employ different switching networks for each of these functional components and may include additional functional components (not depicted in FIG. 1) including, for example, operational subsystem support (OSS) resources.

FIG. 1 also illustrates application server 150 connected to switching network 140. As suggested by its name, application server 150 may host or otherwise implement one or more applications for MCDN 100. Application server 150 may be any data processing system with associated software that provides applications for clients or users. Application server 150 may provide services including multimedia content services, e.g., EPGs, digital video recording (DVR) services, VOD programs, PPV programs, IPTV portals, digital rights management (DRM) servers, navigation/middleware servers, conditional access systems (CAS), and remote diagnostics, as examples.

Applications provided by application server 150 may be downloaded and hosted on other network resources including, for example, content delivery server 160, switching network 140, and/or on clients 120. Application server 150 is configured with a processor and storage media (not shown in FIG. 1) and is enabled to execute processor instructions, such as those included within a software application. As depicted in FIG. 1, application server 150 may be configured to include remote viewer application 152, which, as will be described in detail below, may be configured to enable a user of client 120 of MCDN 100 to remotely view multimedia content.

Further depicted in FIG. 1 is database server 190, which provides hardware and software resources for data warehousing. Database server 190 may communicate with other elements of the resources of service provider 121, such as application server 150 or content delivery server 160, in order to store and provide access to large volumes of data, information, or multimedia content. In some embodiments, database server 190 includes a data warehousing application, accessible via switching network 140, that can be used to record and access structured data, such as program or channel metadata for clients 120. Database server 190 may also store device information, such as identifiers for client 120, and identifiers for various types of MCDN terminal devices.

Turning now to FIG. 2, clients 120 are shown in additional detail with respect to access network 130. Clients 120 may include a network appliances collectively referred to herein as CPE 122. In the depicted embodiment, CPE 122 includes the following devices: gateway (GW) 123, multimedia handling device (MHD) 125, and display device 126. Any combination of GW 123, MHD 125, and display device 126 may be integrated into a single physical device. Thus, for example, CPE 122 might include a single physical device that integrates GW 123, MHD 125, and display device 126. As another example, MHD 125 may be integrated into display device 126, while GW 123 is housed within a physically separate device.

In FIG. 2, GW 123 provides connectivity for client 120 to access network 130. GW 123 provides an interface and conversion function between access network 130 and client-side local area network (LAN) 124. GW 123 may include elements of a conventional DSL or cable modem. GW 123, in some embodiments, may further include routing functionality for routing multimedia content, conventional data content, or a combination of both in compliance with IP or another network layer protocol. In some embodiments, LAN 124 may encompass or represent an IEEE 802.3 (Ethernet) LAN, an IEEE 802.11-type (WiFi) LAN, or a combination thereof. GW 123 may still further include WiFi or another type of wireless access point to extend LAN 124 to wireless-capable devices in proximity to GW 123. GW 123 may also provide a firewall (not depicted) between clients 120 and access network 130.

Clients 120 as depicted in FIG. 2 further include a display device or, more simply, a display 126. Display 126 may be implemented as a TV, a liquid crystal display screen, a computer monitor, or the like. Display 126 may comply with a display standard such as National Television System Committee (NTSC), Phase Alternating Line (PAL), or another suitable standard. Display 126 may include one or more integrated speakers to play audio content.

Clients 120 are further shown with their respective remote control (RC) 128, which is configured to control the operation of MHD 125 by means of a user interface (not shown in FIG. 2) displayed on display 126. RC 128 of client 120 is operable to communicate requests or commands wirelessly to MHD 125 using infrared (IR) or radio frequency (RF) signals. MHDs 125 may also receive requests or commands via buttons (not depicted) located on side panels of MHDs 125. In some embodiments, RC 128 may be operable to configure remote viewing of multimedia content, and/or to activate remote viewing of multimedia content, as will be described in detail below.

MHD 125 is enabled and configured to process incoming multimedia signals to produce audio and visual signals suitable for delivery to display 126 and any optional external speakers (not depicted). Incoming multimedia signals received by MHD 125 may be compressed and/or encrypted, digital or analog, packetized for delivery over packet switched embodiments of access network 130 or modulated for delivery over cable-based access networks. In some embodiments, MHD 125 may be implemented as a stand-alone set top box suitable for use in a co-axial or IP-based MCDN.

Referring now to FIG. 3, a block diagram illustrating selected elements of an embodiment of MHD 125 is presented. In FIG. 3, MHD 125 is shown as a functional component of CPE 122 along with GW 123 and display 126, independent of any physical implementation, as discussed above with respect to FIG. 2. In particular, it is noted that CPE 122 may be any combination of GW 123, MHD 125 and display 126.

In the embodiment depicted in FIG. 3, MHD 125 includes processor 301 coupled via shared bus 302 to storage media collectively identified as storage 310. MHD 125, as depicted in FIG. 3, further includes network adapter 320 that interfaces MHD 125 to LAN 124 and through which MHD 125 receives multimedia content 360. GW 123 is shown providing a bridge between access network 130 and LAN 124, and receiving multimedia content 360 from access network 130.

In embodiments suitable for use in IP based content delivery networks, MHD 125, as depicted in FIG. 3, may include transport unit 330 that assembles the payloads from a sequence or set of network packets into a stream of multimedia content. In coaxial based access networks, content may be delivered as a stream that is not packet based and it may not be necessary in these embodiments to include transport unit 330. In a co-axial implementation, however, clients 120 may require tuning resources (not explicitly depicted in FIG. 3) to “filter” desired content from other content that is delivered over the coaxial medium simultaneously and these tuners may be provided in MHDs 125. The stream of multimedia content received by transport unit 330 may include audio information and video information and transport unit 330 may parse or segregate the two to generate video stream 332 and audio stream 334 as shown.

Video and audio streams 332 and 334, as output from transport unit 330, may include audio or video information that is compressed, encrypted, or both. A decoder unit 340 is shown as receiving video and audio streams 332 and 334 and generating native format video and audio streams 342 and 344. Decoder 340 may employ any of various widely distributed video decoding algorithms including any of the Motion Pictures Expert Group (MPEG) standards, or Windows Media Video (WMV) standards including WMV 9, which has been standardized as Video Codec-1 (VC-1) by the Society of Motion Picture and Television Engineers. Similarly decoder 340 may employ any of various audio decoding algorithms including Dolby® Digital, Digital Theatre System (DTS) Coherent Acoustics, and Windows Media Audio (WMA).

The native format video and audio streams 342 and 344 as shown in FIG. 3 may be processed by encoders/digital-to-analog converters (encoders/DACs) 350 and 370 respectively to produce analog video and audio signals 352 and 354 in a format compliant with display 126, which itself may not be a part of MHD 125. Display 126 may comply with NTSC, PAL or any other suitable television standard.

Storage 310 encompasses persistent and volatile media, fixed and removable media, and magnetic and semiconductor media. Storage 310 is operable to store instructions, data, or both. Storage 310 as shown may include sets or sequences of instructions, namely, an operating system 312, a remote control application program identified as RC module 314, and EPG 316. Operating system 312 may be a UNIX or UNIX-like operating system, a Windows® family operating system, or another suitable operating system. In some embodiments, storage 310 is configured to store and execute instructions provided as services to client 120 by application server 150, as mentioned previously.

EPG 316 represents a guide to the multimedia content provided to client 120 via MCDN 100, and may be shown to the user as an element of the user interface. The user interface may include a plurality of menu items arranged according to one or more menu layouts, which enable a user to operate MHD 125. The user may operate the user interface, including EPG 316, using RC 128 (see FIG. 2) in conjunction with RC module 314. In some embodiments, remote viewing application 152, in conjunction with EPG 316, provides functionality for remote viewing of multimedia content on MCDN terminal devices, as will now be described in further detail below.
